SPECIFICATION forming part of Letters Patent No. 769,347, dated September 6, 1904. Application filed August 20,l 1902. Serial No. 120,292.V (NO model-.

To all wir/m t may/concern: Be it known that I, EDWARD W, JENKINS, of Norristown, county of-Montgomery, State of Pennsylvania, have invented an Improvement in Knot-Tying Devices for Grain-Binders, of which the following is a specification.

My invention has reference to knot-tying devices for grain-binders; and it consists ofcertain improvements, which are fully set forth in the following specification andY shown in the accompanying drawings, which form a part thereof.

I The object of my invention is to provide 'a simple form of knot-tying device-adapted to grain-binders that shall have capacity for tying what may be termed a "weavers knot and at the same time form a knot1 that can bev drawn down on the bundle.

My invention comprehends a rotary looperbill of suitable construction which, in combination with a needle-arm, may be operated to produce what 1s known as a weaversknot, the same consisting in wrapping a loop about -a strand and drawing a portion of the strand beyond the loop through the said loop, as more fully described hereinafter.

this character only one of the ends of the cord passing around the bundle is placed around the looper-bill instead of both ends passing over it, as is customary in knot-.tying devices employing rotary bill-loopers heretofore in use.

My invention comprehends many details of construction which, with the above generic features, will be better understood by reference to the drawings, in whichholder-operating pawl.

Figure 1 is a bottom plan view of a knottier embodying my improvements. Fig'. 2 is a side elevation of same. Fig. 3 is a crosssection of same on line m of Fig. 2 looking In a knot-tier of Fig. I is a plan view of the ,rection and then-a reverse movement.

the knot on a larger scale; and Fig. 17 is a plan view of a portion of the knot-tier, more particularly illustrating the cutter.

2 is the frame or fixed `arm .carrying the knot-tier and is provided with the slots 3 and 3", Figs. I and 17, said parts of the slot being displaced laterally, so as toform a part 3 to cause the cordV leading from the cord-holder through slot 3 and around the bundle, (not shown,) then downward through the slot 3 to one side of" the rotary looper-bill 8 to the needle-arm, and through it in the ordinary way to the spool orcord-box.

The looper 8 is made in the form of a spiral hook having a shoulder 25 and its end slotted at 2l to form a jaw, one part of which is prov vided with a hook or prong 22, the functions of which shoulder and hook or prong being clearly shown in Figs. 9 to 13, inclusive. This looper-bill 8 is provided with a shaft 9, journaled inthe frame 6, and carries at its outer end a pinion l0, which meshes with the rack 1l, secured to the main frame 2. The frame 6 is journaled upon a vertical stud 7,A extendingfrom the frame 14C. It is given a rotary reciprocating movement in tying a knot bya power-applying rod 30 or in any other convenient way. When the frame 6 is rotated, the pinion l0 is rotated by being carried over the tixed rack 11,' and in this way the rotary looper-bill is given a rotation first =in one di- It is also evident that as the frame .6 is oscillated at the same time that the looper-bill is rotated the said looper-bill has its axis of rotation constantly shifting in the act of tying the knot, as will more fully appear farther on. This is important, as it enables the bill of the loo looper to properly loop and enter between the cords leading to the holder and needle-arm and grasp and withdraw the part thereof next to the needle-arm. The smooth surface 13 of the frame 6 acts as a guide for the cord in passing to the cord-holder.

The frame 6 has journaled upon it eccentrically to the stud 7 an inverted crown-w heel 16,constituting one member of the cord-holder mechanism, the other member being the pivoted clamp 26,. The wheel 16 has its bearing close to its periphery, so that there is no tendency to rotate too freely, and has its periphery formed with serrations 18 at intervals separated by two notched portions 19 and 20` as fully shown in Fig. These notched portions are adapted to receive the cord and drag it between the clamp 26 and the crown-wheel itself and so that it lies across the serrations 18, which hold the cord and pull the loop off the knotter, and thereby insures the closing of the loop. The clamp 26 is pivoted to the frame 6 at 27 and is curved to fit snugly against the periphery of the crown-wheel 16, Fig. 4. This clamp is pressed against the crown-wheel by a spring 28, whose tension is adjusted by screw 29. In this manner any degree of nipping and holding pressure may be secured between the parts 16 and 26 to insure the cord-holder performing the functionV of holding the cord.

The crown-wheel 16 is preferably not a true circle on its periphery, being flattened or camshaped between each pair of the parts 18, as shown in Figs. 1 and 4, the function of which is to more readily catch the cord and drag it around into the clamp 26.

At or about the center of the crown-wheel 16 is a hub 17 in which is journaled the shaft of the pivoted knife 31, having the cutting edge 32. The heel of the cutter is provided with a pin 33, which extends upwardly through a slot 34 in the main frame, Figs. 1, 3, and

17 This slot 34 is shaped, as shown, so that when the looper-bill is forming the loop upon itself the cutter will be thrown back away from the bill and when the looper-bill is retracing its movement and completing theknot thedcutter will be thrown forward to cut the cor The crown-wheel 16 is provided withafourtoothed star-wheel 36, which is acted on by a pivoted spring-controlled pawl 37, which is carried on the main frame 2 and hooks upon the teeth of the star-wheel when the latter is moved in an arc about 7 asa center by the rotary reciprocating movement of the pivoted frame 6, above described. In this manner the crown-wheel 16 is intermittently rotated, so as to bring one of the serrated parts 18 in position in front of the pivoted holder-arm 26, Fig. 4. As this crown-wheel is rotated the cord, which has been laid in the notch 2O bythe combined action of the needle-arm and looper-bill, is dragged forward into position between the serrated part 18 of the crownwheel and the surface of the cord-holder arm 26, where it is lirmly held under the action of the spring 28, whose tension may be adjusted by the screw 29, as before stated. A springactuated pawl 38, also pivoted to the main frame 2, act-s upon the star-wheel to prevent it turning too far when the cord is being pulled by the looper-bill so as to turn the crownwheel 16 and make it give up cord to form the knot. A spring 39 extends between the heels of the friction-pawl 38 and the actuating-pawl 37, so as to impart to both of them a spring' action. Any other spring mechanism may be employed, if so desired.

When the frame 6 is oscillated, the starwheel is moved toward lthe pawl 37; but at the same time the action of the looper-bill in taking up the cord in forming the knotcauses the crown-wheel 16 of the cord-holdingmechanism to rotate at a corresponding speed, and this keeps the pawl 37 in contact with the tooth of the star-wheel. While this action is being' performed the star-wheel will be rotating toward the pawl 38 and is stopped only when the end of said pawl is received in the base of the notch between the two teeth. ln this way there is no possibility of the crownwheel 16 being turned to free the cord before the knot istied, which is a most important feature, as such liberation would destroy the possibilityof tying the knot. Aftcrthe starwheel has seated itself positively upon the end of the pawl 38 the linal movement will cause a tooth of the star-wheel to snap back of the pawl 37. The reverse movement of the frame 6 will cause the axis of the crownwheel to move away from the pawl 37, and hence its tooth, which is hooked by the end of the pawl 37, will be held while the starwheel is bodily moved with frame 6 about axis 7, which action will cause the star-wheel to be turned upon its own central axis and snap a tooth of the said star-wheel under the end of the pawl 38 to again bring the crownwheel and its star-wheel into position to give up cord in the formation of a new knot.

31 isa cutter having the sharp cuttingedge 32 and is provided with a pin or stud liournaled in bearing 17, as clearly shown in Fig. 3. 1n this manner the cutter is adapted to move in the arc of a circle having as its axis of rotation the center of the crown-wheel 16. The rear end of the cutter-arm 31 is provided with an upwardly-extending pin 33, which works in a cam-slot 34 in the main frame 2. The object of this pin and slot is to cause the cutter to have a rotary reciprocating motion relative to the cord-holder during the operation of the tying of the knot. Its action is produced by oscillating the frame 6 about 7 as an axis, and thereby swinging the fulcrum-point 17 of the cutter, as indicated by the arrow in Fig. 17. This causes the pin 33 to work in the cam-slot 34 of the stationary main frame IOO 2, andL consequently produces an oscillation arrow in Fig. 17 the cutter31 will be caused to swing rapidly from the position indicated into lsuch a position that the cutting edge 32 would approximate the position indicated by the number'16 in this figure. The extent of motion is immaterial beyond the fact that-the cutter must have capacity for swinging back out of the way of the slot 3 of the main frame, through which the cord passes toV the bundle and needle-arm.

It will be seen that the cord-holding parts 26l and 18 of the cord-holder are greatly to one side of the cord-slot 3 in the frame or breastplate 2 and also that the looper-bill 8 is arranged between said cord-holding parts of the cordholder 'and the slot 3, so that the cord extending from the cord-holder is caused to lie substantially diagonal across the looper-bill in reaching the bundle. It will also be observed that the needle-arm 4 causes the cord leading from it to the bundle to lie in alinement with the slot 3, and hence to one side of the looperbill, so as not to wrap about it when brought in position by the needle-arm. y

It is wholly immaterial what position the knot-tier may assume in the grain-binder, as 1n some classes of machines the bundle 1s` formed above the knot-tier, whereas in other types of machines it is formed below.` In Figs.2 and 3 the position of the knot-tier is as if the bundle were to be formed above the knot-tier; but it is to be understood that this is purely arbitrary and wholly immaterial to the invention forming the subject-matter of this application.

The operation of the machine will -be understood and may be described as follows: Assuming that the parts of the machine are inthe position indicated in Figs. 1, 2, 3, and 4.l the cord will pass from the cord-holder around the neck of the looping-bill 8, thence through the slot 3a and around the bundle` thence through the slot 3 to the needle-arm 4, with the cord resting in a slightly-grooved portion 15 on an extension or bracket 14 of the main frame, which projects below the cordholder and upon which the stud 7 is formed.

When this position is assumed,the cord leading from the needle-arm is practically straight, but the cord leading from` the cord-holder extends diagonally around the looper -.bill and the parts are as indicated in Figs 1, 2, 3,'and 8, the former and latter views being vrelatively inverted with respect to the other of said views-namely, Figs. 2 and3. The frameis then'oscillated about'stud 7 as an axis,(describ ing an arc from left to right in Fig. 1.) `The effect of this is to produce a rotation of the looper-bill, causing it to act upon the cords,

' ample.

cords-thatis, toa position which would corl respond to the iigure`16in Fig. 17, for ex- A reverse movement ofthe frame 6 now takes place, and in describing thelarcl from the right to the left backto its original position the looper-bill 8 is rotated in the reverse direction to its former rotation and successively' assumes the position indicated in Figs. 12 to 15, inclusive, and ultimatelythe position indicated in Figs. 1, 2, 3, and 8, such movement of the looper-bill having completed the knot, as indicated in Figs. 15 and 16. Simultaneously with this ,reverse action of the looper-bill the V cord at the end adjacent to the needle-arm will have been drawn bythe looper-bill from the recessedy portion "15 of the frame 14 laterally toward the throat 40 between said frame 14 andV the frame 6. Fig. 1, and in this manner be permitted to enter the notch 20 of the crown-wheel 16 ofthe cord-holder, having been guided therein by theV linclined edge thereof, Fig. 5, so that it is in position to be dragged into the cord-holder-grippingv surfaces upon rotating the. crown-wheel. rlhe star-wheel 36 is also during this reverse movement caused to be rotated by being dragged against the spring-pawl 37, which has been hooked upon one of its teeth. When this rotation of thestar-whee'l and the crownwheel of the cord-holder takes place, the cord is dragged between the serrated portion 18of the crown-wheel and the friction-surfaces of the cord-holder arm 26, and all surplus cord between the said cord-holder and looper-bill is thereby taken up. At this time the cords are in the position indicated in Fig. 14-that is,' i

both terminals of the knot are in the cordholder; but the terminal leading from the cord-holder lies in notch -19 of the crownwheel, and the terminal leading to the needle-` arm lies in notch 20. At this juncture thel cam-slot 34, acting upon the pin 33 of the cut-` ter 31, will causel it to rapidly oscillate and bring the cuttingedge 32 across the cord last gripped ,by the cord-holder and sever the-cord at a point between the cord-holder and the looper-bill, as indicated at 5b in Fig. 15. Thisv severing of the cord, however, should not, f preferably, take place until after the looperbill has positively drawn up the loop, as indicated in Fig. 14. While this action of the looper-bill is taking place the other end, 5a, of

aro

Figs. 9 and 10.

been completely formed and drawn tight, the cord-holder crown-wheel 16 by rotating under the action of the pawl 37 causes its gripping-surface 18 to move away from the looperbill and releases the knot end 5L after pulling said end against the action of the looper-bill,

but not until the final movement of the looperbill has drawn the loop 5C, Fig. 15, to such extent that the end 5b passes through the knot, this action taking place in such a manner as to draw the knot close to the bundle, withthe result that the bundle is tightly tied and all looseness prevented. In all knotters heretofore made with which I am familiar the looper-bill produces slackness in finishing the knot instead of taking up the surplus cord between the knot and the bundle, and I therefore consider this a very important part of my invention. The finished knot, which may be designated as a weavers knot, is shown in Fig. 16 and as far as I am aware has never before been tied by machinery.

The action of the looper-bill on the cord in forming the knot is shown in Figs. 8 to 15, and for convenience these figures are inverted from the positions of the corresponding parts that are shown in Figs. 2 and 3. In Fig. 8 the cord that passes from the cord-holder alone is wrapped around the neck of the looper 8, whereas the other cord end is guided to one side of the looper-bill and assumes a position indicated at 5 in Fig. 1. As the looper-bill is rotated in the direction indicated by the arrow it will be seen that the cord around its neck is twisted into a loop and dragged around by the shoulder 25 on the looper-bill, and at the same time the slotted nose or jaw of the bill is moved over and engages the cord leading to the needle-arm, as indicated in A further rotationof the looper-bill causes the jaws of the nose of the bill to approach the cord leading to the needlearm and receive it in its slot, as indicated in Fig. 12. This having been accomplished, the looper is rotated in the reverse direction, as

indicated by the arrows in Figs. 13, 1&1, and

15. The cord received in thejaw of the looperbill is caught by the prong 22 therein, as

shown in Fig. 13, and is thereby dragged backward through the loop previously formed about the neck of the looper `from the cord leading to the cord-holder-namely, the loop formed in the iirst instance about the looperbill. This action is indicated in Fig. 14, which shows the loop-shed from the looper-bill so as to be free and between the cord-holder and the bundle and with the cord from the needlearm hooked onto the prong 22 of the looperbill in the act of being drawn through the loop of the knot. .lhe cord leading to the needle-arm is at this time clamped in the cordholder and is eut by the cutter 32 between the knot and the cord-holder. The looper in continuing its movement drags the loop in a direction away from the cord-holder and also away from the bundle, which action induces the knot to work its way up to the bundle, thereby removing all slack froln the cord extending around the bundle. The cord leading from the loop 5" is .then cut by the cutter 32 between the knot and cord-holder, as i11- dicated in Fig. 15.

In the linal movement of the looper-bill when returning to its original position the free end of the loop 5 is pulled through the knot as the bundle is discharged, though this is not essential. rI`he parts are then in position for once more passing the cord around a new bundle and delivering it to the knetter for repeating the operation. In doing this the cord passes from the cord-gripping part 18 of the crown-wheel through notch 20, then backward around the back of part 18 through notch 19, then around the looper to the bundle. The cord then returns and passes into the next notch 2O of the crown-wheel, so that the two ends of the bundle-loop are in ditl'erent notches 19 and 20.

rIhc shoulder 25 of the looper-bill is very important in that it positively holds the loop out on the periphery of the curve in proper position upon the looper-bill during the act of making the knot-namely, a position which will enable the loop to be shed from the end of the bill after the prong 22 has grasped the cord and started to pull it through the loop. It also draws a proper amount of cord from the holder to tie the knot.

It will be observed that in my improved knot-tying device only one cord is wrapped about the looper-bill in the initial step and that this cord is lirst looped and wrapped about the other cord end, and through the loop thus formed the distant end of the said other cord leading' to the needle-arm is grasped and drawn. Incidental to said operation the two ends-namely, the oneleading to the cordholder and the one leading to the needle-arn1- are twisted together, as indicated in Figs. l1 and 12, prior to drawing the end of the cord through the loop in completing the knot, the said twisting operation simply accomplishing the result of enabling the prong to grasp the cord after it has been passed about both ends of the loop portion, as shown more fully in Fig. 13. These features, as far asl ain aware,

lOO

and an oscillatory motion about another axis 7, transversely arranged in line with its own axis. The result of this is that the bill when `performing its rotaryreciprocating motion is .enabled to assume different positions .relatively to the cord ends as-delined by the fixed .frame and n eedle-arm, so that the looper-bill -nose is enabled to pass by the cord leading to 4the cord-holder and grasp the cord leading to i the needle-arm during. the latter part of the formation of the knot, all of which is important in producing a practical construction of apparatus.

While I have shown the apparatus as I have practically constructed it for use and which I have found-most excellently adapted to commercial purposes, I do not limit myself to the details or to the special relative movements of the parts, as my invention is intended, broadly, to include a rotary reciprocating looper device combined in any suitable manner with the necessary additional mechanism, including the cord holder and cutter, whereby it will accomplish the tying ofthe cord to produce the knot herein shown and'what may be termed a weavers knot. Therefore,- while I prefer the construction shown, I do not confine myself to the details, as they may be varied as found most convenient for any Vspecial application of my invention. l Having now described my invention, what I claim as new,'and desire to secure by Letters Patent, is` 1.
